For those that have never experienced it, you should try Lenovo Thinkpads some day. On the underside every screw has a little pictogram so you can easily tell which ones are needed to remove the keyboard versus the hard drive for example.
You can enter a system's serial number at http://support.lenovo.com/en_US/product-and-parts/partsLooku... and it will tell you exactly which parts went into it. For example some systems may have exactly the same model number, but some are made with LG panels and some with Samsung. This will tell you exactly.
IMHO they have done an excellent job. They even design the keyboard and system so that fluid on the keyboard drains out the bottom. (Note it isn't waterproof, just a good effort to ensure a minor spill doesn't destroy the machine.) One example video is at http://www.youtube.com/watch?v=d7cvi00OZDM
And the proof is in the pudding - a friend who managed to break one of her hinges was able to lookup the exact part, order it, take the machine apart and replace the hinge and put it all back together without any difficulties or guesswork.

Then they have hardware maintenance manuals at http://support.lenovo.com/en_US/guides-and-manuals/detail.pa... which show you exactly how to take the laptop apart and change/repair parts.
